GLUE-STOCK WASHER.

SPECIFICATION forming part of Letters Patent No. 276,040, dated April 17, 1883.

I Application filed January 30, 1883. (No model.)

To all whom it may concern Be it known that I, WILLIAM A. HOEVELER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Glue-Stock Washers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure l is a transverse vertical section on line 00 a: of Fig. 2 of my apparatus. Fig. 2 is longitudinal vertical section of the same. Fig. 3 is an enlarged plan illustrating the screen and hinged covers, one being open and one closed. Fig. 4 is a detail of the hub, stems, and part of one paddle.

This invention relates to the construction of apparatus for washing glue-stock; and it consists in the novel features and their combinations, as hereinafterfully set forthand claimed. In apparatus for this purpose the stock is damaged by being broken up too much, and considerable loss results, besides, from the fact that the small particles are allowed to escape with the wash-water. By myconstruction and arrangement these defects are remedied and other advantages derived, as will be hereinafter described.

I construct the apparatus in the form of a rectangular trough -like structure, with its sides and ends A substantially water-tight by means ofthe double walls a a. The upper portion of the interior is occupied by the swinging wash-box B, semicircular in shape, with flat sides and rounded bottom throughout, the bottom being perforated. Upon a transverse shaft, 0, journaled at the axis of box B, I set a paddle-wheel composed of a suitable hub, d, and adjustable paddles, each composed of the radial stem 6 and the blade for spoon. The spoons f are set on the stems 6, so as to be capable of being reversed or turned half-way around, more or less. One side of the spoons f is rounded off, so that while passing through the stock the latter will not cling to or remain upon it. The other side of the spoons is flat, but slightly skewed or beveled, so that when turned to face with the gathersup the stock and holds it till out of the box B, but upon further elevation causes it to roll or slide along the paddle to a predetermined point, where it falls 0E gently into a discharge-spout, g, which carries it off for further treatment practically undamaged. During the operation the box B and the body A are kept supplied by a stream of clean or chemically-prepared water, and the wheel 6 f revolves slowly in the box, the edges of'the paddles sweeping around, while the box B or its bottom is kept oscillating, thus preventing an injurious clogging of the perforations in the box-bottom. After the stock is placed in box B and the latter filled with sufficient water, the wheel 0 fis caused to slowly revolve (by motive or hand power) with the rounded sides of the spoons f presented forward. This operation thoroughly agitates and cleanses the stock, while therounded form ofthe spoons prevents the breaking up of the natural condition of the stock. I gather the finer particles as follows after they have escaped through the perforated bottom of the washbox B: At the lower part of trough A, elevated on cross bars or blocks h, I place two parallel strips, 6, and between these, which are grooved to form ways, It, inside, I set a long screen, Z, placed on rollers m, and movable thereby on the rails or ways 70. To give movement to the screen Z, I attach to its end a rod, n, which projects outwardly through the walls a a by means of the packing-box p and cap or door (1, which, when opened, allows the withdrawal of the screen 1 and its burden. The shaking of the screen is accomplished by a suitable motor applied to rod 11., and is kept going during the operation, as required. To the strips 5, which are placed at a little distance from the side walls, a, (to leave a passage for the water and refuse to go through,) I hinge the two doors 1", which shut down upon the rod 8 as a support, in which case nothing can fall upon the screen, or which open up and rest against the sides a a, in which case the screen is exposed and the side passages closed by the doors 1*. During the initial or rough washing stage the doors 1" are kept closed and the dirty water and refuse pass freely down the side passages and out at a suitable opendirection ofmotion of the wheel it not only ing at the bottom. After this stage it becomes desirable to catch the particles which get detached from the stock in box B and come through theperforations therein. I then open up the doors 1', thus closing the side passages and compelling all the water and small stock to go to the screen Z, which catches the remaining stock. When sufficiently accumu lated the screen may be drawn out and the stock thereon removed. When the main body of stock in box B has been cleansed the paddles or spoons f are reversed, so as to present their flat skewed faces to the stock, and in revolving now the paddles gently lift the stock and discharge it into the spout or hopper g. The washing andoremoval of the stock when washed is thus accomplished without further manipulation than to reverse. the paddles, which obviously could be done by a reversinggear on the motor, thereby reversing the direction of movement of the paddle-wheel.

Instead of the whole box B being oscillated I back and forth, its bottom may be set on slides orrollers and oscillated, while the sides remain stationary. I y

In the drawings I have shown the box B as hung upon the shaft 0 as a center; but as the provision of means of reciprocating or oscillatin g the box or its bottom is within the skill of any machinist I do not describe any specific form. As the box with its contents will be very heavy, I prefer a special motor for it, which also may be geared up to reciprocate the screen I.

Instead of the door q as located in Fig. 2, I can locate it as. at q, same figure.

I claim as my invention- 1. In a glue-stock washer, the combination of a rotary paddle-wheel, e f, and a semicircular wash-box, B, having rounded perforated bottom, substantially as described.

2. In a glue-stock washer, the combination ofa semicircular wash-box having a perforated bottom, and a rotary paddle-wheel having its paddles rounded on one side and flat on the other and capable of having either side presented to the direction of motion, substantially as described.

3. In a glue-stock washer, the combination of a semicircular wash-box having a perforated bottom, and a rotary paddle-wheel having its paddles rounded on one side and fiat and beveled or skewed on the other, and capable of having either side presented to the direction of motion, substantially as described.

4. [n a glue-stock washer, the combination, with the perforated principal wash-box, of a screen located beneath the wash-box and having passages on its side or sides, and a hinged door or doors adapted in one position to cover said screen and in the other position to close said side passage or passages, substantially as described.

5. In a glue-stock washer, the combination of a rotary paddle-wheel, ef, and a semicircular wash-box, B, having rounded perforated bottom, said box B or its bottom constructed and adapted to oscillate around its axis, sub stantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
